The Hidden Infrastructure Behind Your Walls
Every switch you flip, every outlet you plug into, and every appliance that runs in your RV depends on wiring that's hidden behind walls, under floors, and above ceilings. When that wiring fails, the symptoms can range from a single dead outlet to a complete system shutdown. And in the worst cases, damaged wiring can start a fire without any warning at all.
RV wiring takes more abuse than residential wiring ever will. Every mile you drive creates vibration that flexes connections, loosens terminals, and fatigues wire strands at junction points. Road shock from potholes on US-1 or I-95 in Indian River County sends jolts through the chassis that residential wiring never experiences. Over time, connections that were tight at the factory work loose, and that's when problems start.
Vibration Damage
Vibration is the number one cause of wiring failures we see in RVs around Sebastian. Wire nuts, crimp connectors, and screw terminals all loosen gradually with road vibration. A connection that develops even a tiny gap starts to arc under load. That arc generates heat, which corrodes the connection further, which increases resistance, which generates more heat. It's a cycle that ends in a melted connector or a tripped breaker.
The most vulnerable locations are junction boxes near wheel wells, connections under slide rooms that flex every time the slide extends, and wire runs that pass through structural members without proper strain relief. We check all of these locations as part of any wiring diagnostic.
Rodent Damage
Florida's warm climate means rodents are active year-round, and they love RV wiring. Rats and mice chew through wire insulation to access the soy-based coatings that many manufacturers use. A single mouse can strip insulation from 6 to 10 wires in one night. We've pulled open underbelly panels on RVs stored in Sebastian, Fellsmere, and Barefoot Bay to find dozens of chewed wires tangled together.
Rodent damage is particularly dangerous because it often strips insulation from multiple adjacent wires. When bare conductors touch each other or the metal frame, you get short circuits. When a hot wire touches a ground wire, the breaker should trip. But if the rodent chewed the ground wire too, the breaker won't trip and the fault just generates heat silently. That's a fire waiting to happen.
Salt Air Corrosion
Sebastian sits right along the Indian River Lagoon, and that salt air gets into everything. Exposed terminals, wire connections in junction boxes, the contacts inside your breaker panel, and the pins in your shore power inlet all corrode faster here than they would 50 miles inland. We see green copper corrosion on terminals that were clean just 12 months ago.
Corrosion increases resistance at every contact point. Higher resistance means more heat under load. That heat accelerates corrosion further. We use dielectric grease and marine-grade connectors on every repair to slow down the corrosion cycle in this coastal environment.
GFCI Outlets and Breaker Panels
NEC Article 551 requires GFCI protection on all outlets in wet locations: the bathroom, kitchen, exterior outlets, and any outlet within 6 feet of a water source. In Florida's humidity, GFCI outlets work harder than they do in dry climates. Moisture intrusion, condensation, and even high ambient humidity can cause nuisance tripping. We'll determine whether your GFCI is tripping because of a genuine ground fault or because the outlet itself has failed.
Breaker panel issues are less common but more serious. Loose bus bar connections, corroded breaker contacts, and overloaded circuits all show up in the panel. A full panel replacement costs $500 to $900 and is worth it when the panel has multiple failing breakers or visible heat damage.
What Wiring and Circuit Repair Costs
Single circuit repair or outlet replacement runs $125 to $300. Rodent damage repair depends on how many wires were chewed, typically $200 to $500. Breaker panel replacement costs $500 to $900. Full section rewiring falls between $300 and $600. We always provide a written quote after diagnosis, and the diagnostic fee gets rolled into the repair cost if you proceed. All work meets NEC Article 551 specifications for RV electrical systems.

Wiring & Circuit Repair FAQ
Watch for lights that flicker or dim when other devices turn on, a burning or melting plastic smell near outlets or the breaker panel, breakers that trip repeatedly on the same circuit, outlets that are warm or discolored, devices that work intermittently, and any visible scorching or melting on wires or connectors. If you feel a tingle or shock when touching metal surfaces in your RV, that's an urgent grounding problem that needs immediate professional attention.
Yes, and it's one of the leading causes of RV fires. The National Fire Protection Association reports that electrical failures cause roughly 30 percent of RV fires. Loose connections generate heat through resistance. Corroded terminals arc under load. Rodent-chewed insulation exposes bare copper that can short against metal framing. In Florida's heat, wiring that's marginal in cooler climates can reach ignition temperatures faster because the ambient temperature is already high. Any wiring problem that involves heat, smell, or sparking should be treated as urgent.
We use a systematic approach. First, we identify which circuit is affected by checking the breaker panel or fuse block. Then we disconnect loads one at a time to isolate the fault. We use a circuit tracer to follow the wiring path through walls, floors, and ceilings without tearing anything apart. A multimeter checks for continuity and resistance at each junction point. In most cases we can pinpoint the exact location of a short within 30 to 60 minutes without cutting open walls.
GFCI outlets trip when they detect a ground fault, which is current flowing through an unintended path. In Florida RVs the most common causes are moisture intrusion into an outdoor outlet or junction box, a failing appliance like a water heater element that's leaking current to ground, corroded wiring connections that allow current leakage, and condensation inside walls during humidity swings. Sometimes the GFCI outlet itself has failed and needs replacement, which costs $125 to $175 installed.
Rewiring a single circuit like a slide motor or a dedicated outlet run costs $125 to $300. Rewiring a larger section such as the bedroom or kitchen circuit group runs $300 to $600. A full breaker panel replacement with new home runs costs $500 to $900. The main variable is accessibility. Wiring that runs through open areas is fast to replace. Wiring that's buried behind walls, under floors, or routed through tight structural channels takes more time and costs more.
A straightforward issue like a tripped breaker, a bad outlet, or a blown fuse takes 15 to 30 minutes to diagnose. An intermittent problem like flickering lights or a circuit that works sometimes typically takes 30 to 60 minutes with a circuit tracer. Complex issues involving multiple circuits or hidden damage from rodents or water can take 1 to 2 hours. We charge a flat diagnostic fee that gets rolled into the repair cost if you proceed with the fix.
